Abstract

We report the first records of the ingestion of a toxic California newt (Taricha torosa) and a particular species of Jerusalem cricket (Stenopelmatus fuscus) by a Great Horned Owl (Bubo virginianus). This is one of only a few records of avian predation on this genus of toxic newt. Ingestion of the extremely poisonous tetrodotoxin present in the newt's skin was likely the cause of the owl's death.
